The Intel Arc A770 is the objective winner of this comparison, securing victories in eleven out of thirteen measured categories. Its most significant technical advantage is its FP16 performance, which is 262% higher than that of the NVIDIA GTX 1660 Ti. This substantial lead in computational capability establishes the Intel Arc A770 as the superior choice for users prioritizing raw processing power and modern hardware specifications across the vast majority of the evaluated metrics.

Users who require maximum computational throughput should select the Intel Arc A770 for its dominant performance advantage. Conversely, the NVIDIA GTX 1660 Ti is the better option for those who prioritize power efficiency, as it maintains a 47% advantage in TDP. Choosing between these two components depends on whether your primary requirement is the high-performance output of the Intel card or the lower power consumption profile offered by the NVIDIA alternative.
